The survey form was developed to minimize excessive writing in the field. With the exception of Part
I ( General Information), completing the survey primarily required a check or circle for the appropriate
choice for each applicable question ( see Appendix 3). Comment lines provided the surveyor the
opportunity to clarify a BMP issue not captured by a yes or no response. Based on field testing, the
survey itself required 15 - 20 minutes to complete. After completing the survey, a site evaluation/ FPG
compliance notification component was completed. This FPG compliance information has been
compared to the survey data on an annual basis. The data was also compared to other FPG
inspections completed outside of this project. The survey did not replace and/ or serve as an
alternative product to NCDFR’s normal forest management record- keeping. All FPG compliance
issues discovered during completion of the survey were managed via NCDFR’s FPG policy and
procedure.
4. Compiling the Survey Data
The NCDFR’s Forestry NPS Unit compiled and tracked survey data at the Raleigh Central Office
( CO). Completed surveys were sent to the NCDFR CO monthly. A survey copy was kept in the
district office from where the survey was completed for record- keeping purposes. The Forestry NPS
Unit office assistant compiled the survey data in a Microsoft ® Access ™ database.
5. Quality Control
The Forestry NPS Unit staff completed quality control by randomly selecting sites where surveys
were completed to ascertain the accuracy and completeness of the surveys. A number of surveys were
also completed in tandem ( field surveyor and CO representative). In this case, each party completed
the survey before selections and ratings were compared for discrepancies. If errors or discrepancies
were found, the surveyors reviewed and discussed the information to resolve concerns.
6. Analyzing the Survey Data
The BMP Implementation Survey results were based on the sum of the applicable BMP condition( s)
found on each site ( see Table 1 and Figure 2 below for an example). All survey results were derived
from query reports from the database. The BMP implementation data was then assessed to provide
specific physiographic regional results ( see Statistical Analysis).
The survey findings are based on the evaluation of more than 43,000 BMP conditions representing
more than 5,000 practices on 565 sites. Appendix 5 provides state maps that represent the total
number of surveys completed in each county. Appendix 3 contains a copy of the survey.
7. Statistical Analysis
The BMPs evaluated represent a sample set of the total population of BMP conditions implemented on
harvesting operations across the state during the survey timeframe. Based on the survey procedure, the
sample statistics below express the quality of the survey’s BMP implementation estimate.
BMP Implementation Estimate ( f):
f = BMPs implemented f = 15,720 BMPs implemented f = 0.82
BMPs evaluated ( n) 19,217 BMPs evaluated ( n)
